CIGAR-BUNCH MACHINE.

Application filed February 7, 1925.

My invention relates to cigar bunch machines of the automatic type and more particularly to an improved mechanismifor applying paste to the filler hinder.

Heretofore cigar bunch machines of the automatic type have been provided wlth mechanism for applying paste to the filler binder after it has been placed on the rolling apron. Such mechanism as has been heretofore in use has proved substantially satisfactory, but is open to objection as overcomplicated and difficult of ad ustment. Further, such. mechanism is objectionable in that in its construction no provision 18 made for rendering it inoperative with the result that if the continuity of production is interrupted paste is smeared on the roll1ng apron and where any interference with the paster arm occurs breakage results.

Now it is the object of my invention to provide a paster of novel construction which will be efiicientand accurate in operation and further to provide a paster which may be thrown out of operation independently of the operation of the bunch machine as a whole and which will automatically go out of action on the meeting of any obstruction.

Having now indicated, in a general way, the nature and purpose of my invention, I will proceed to a detailed description thereof with reference to the accompanying drawings, in which I have illustrated a preferred Fig. 1 is a side elevation, partly in section, of a portion of a cigar hunch machine provided with a paster embodying my invention.

Fig. 2 is a detail view showing a paster guide cam.

Fig. 3 is a plan view of a bunch rolling table and paster.

Fig. f is a rear view of the paster showing method of mounting.

Fig. 5 is a plan view of the paster wheel showing adjustable mounting on the paster arm. 41 represents the frame of a cigar bunch machine upon which is mounted a rolling table 5 on which is operated in the usual manner a rolling apron. Mounted in suitable hearings in the frame is a cam shaft a driven through gearing d and carrying a cam 6, having a cam surface formed on its side, and a pulley f. i h

The frame is apertured, as at g, for the Serial No. 7,487.

passage of a curved lever h pivotally mounted as at i and provided at its lower end with a cam follower wheel 3'. A spring attached to the frame and to the lever it above pivot 2' tends to hold the cam follower against the cam surface formed on cam 6,

so that as cam e revolves the lever Will be oscill'ated on its pivot.

Removably secured to the frame adjacent the aperture 9 is a bracket Z upon one side of which is mounted a receptacle m adapted to hold a supply of paste, in which a wheel a, mounted on a shaft 0 j ournalled in the side walls of the receptacle, is adapted to dip. A'pulley p is mounted on one end of shaft 0 and receives a belt 9 which passes around pulley 7 on cam shaft 0, so that as the cam shaft revolves the wheel a is revolvedin the paste supply. An idler pulley r is provided for the belt.

.To the upper end of lever h is connected, by means of a slot and pin connection, one end of a paster arm 8, the other end of which receives the threaded end of a stem 2? upon the free end of which is revolubly mounted a paster wheel u, the periphery of which is channelled and milled as shown in Fig. 5. The stem 6 is secured in adjusted position by means of a lock nut Q).

Mounted on the side of the paster arms intermediate its ends is a roller w adapted to follow a guide cam on mounted on bracket,

Z. The guide cam, as shown in Fig. 2, presents from'its rear to its front an upwardly slanting surface m with a drop-off at the forward end onto a lower surface 00 which extends on a substantial level to join the surface :0 below its forward end. The front portion 3 of the surface 00' is made separate and pivotally mounted as at y in order to permit the roller w to lift it against the ten sion of a spring, indicated at 3, and pass from the lower surface so to the surface :0,

as clearly shown in Fig. 2. Beneath theforward end of surface a is positioned a pivotally mounted buffer a, the free end of which is yieldingly maintained beneath the end of surface 00 for the reception of the roller w by means of a spring 2. When the roller reaches the end of cam, surface 00, it turns on its pivot under the weight of the .arm and passes the roller down to the buffer a, which, under the weight of the paster arm, i's' depressed against its spring and serves to let theroller down easily on the cam surface an. The spring 3 returns the forward portion y into line with the cam surface 00 when the roller clears it.

In operation, assuming the cam shaft 0 to be rotating, the wheel at will be rotated in the paste and the lever it will be oscillate-d about its pivot by cam 6. Assuming now that the lever h is in its rearward position, as indicated in dotted lines, Fig. 1, the paster arm will be retracted and lowered so that the paster wheel will be in contact with and receive a supply of paste from the wheel "n and the roller '10 on the paster arm will be at the rear of guide cam As the lever 7b is moved forward by cam e, the paster arm will move forward andbe raised by the cam surface 00, until the roller 10 reaches the forward end of surface 00 at'which time the paster wheel 10 will be above the rolling table 6, at a point desirably located in reference to a binder previously placed on the table by the usual transfer device. As the roller 'w leaves the cam surface 00 and is let down to surface 00, as shown in F ig. 1, the end of the paster arm and the paster wheel is dropped into contact with the binder on the rolling table. At this point, the lever it will have reached its forward position. On movement of the lever it toward the rear, the past-er arm is retracted and the roller to following the cam surface at permits the paster wheel to roll over the desired portion of the binder and apply paste. As the roller 'w approaches the rear of cam surface 00, it contacts with the underside of the pivoted portion 3 of the surface 00 and lifts it to clear a path to surface as, as indicated in Fig. 2, down which the roller travels permitting the end of the paster arm to lower until the paster wheel u again contacts with wheel a. 1

It will be observed that in the device embodying my invention the paster may be thrown out of operation by merely drawing lever 72 and cam follower j away from earn (2 against the action of spring 71:. This may be accomplished manually by simply holding the paster arm in retracted position or by means of a suitably located lever to which is connected one end of a cable l, the other end of which is connected to lever it. As shown in Fig. 1, if the cable be led to a point not substantially behind lever it, there is provided a conduit 5 through which the cable passes and which serves as a guide and prevents undue wear on the cable. It will be noted that should the paster arm or other part of the mechanism meet with an obstruction, such obstruct-ion would only need to be sufficient to overcome the tension of spring'is to automatically throw the mechanism out of operation without possibilityof damage.

It will be further observed that-in accordance with my invention the paster canbei assembled and applied as a unit/and provision is made for readily adjusting the paster wheel either through adjustment of the bracket Z or adjustment of the paster .wheel through adjustment of stem 25 or through adjustment of both.
